California Storms: Wettest Water Year, So Far, In 122 Years Of Records

Fueled by a parade of “Pineapple Express” storms, California is in the midst of its wettest water year in 122 years of record-keeping, according to federal scientists. Between October 2016 and February 2017, California averaged 27.81 inches of precipitation, the highest average since such records began being kept in 1895, according to data released Wednesday by the National Centers for Environmental Information, part of the National Oceanic and Atmospheric Administration.

 

Lake Oroville At Highest Level In Nearly 3 Weeks, Spillway Work Continues

The water level at Lake Oroville is rising to its highest level in nearly three weeks. The gates to the reservoir’s main spillway were closed back on February 27th so that crews could work on removing a massive pile of debris at its base. On Wednesday evening, the lake neared 860 feet — a level managers had earlier said they did not expect to reach during the spillway closure. The lake’s capacity tops off at 901 feet. California Department of Water Resources Spokeswoman Lauren Bisnett says the elevated level is being closely monitored.

OPINION: Overhaul California’s Water System With 21st Century Flood Solutions

The dramatic spillway failure at Oroville Dam sparked a national conversation around the status of dams throughout the West. But dams are just one small part of the “gray” infrastructure designed to control flows, hem in rivers and transport water around the state. California’s flood and water-management system needs an overhaul to address everything from eroding levees to parched Central Valley aquifers and collapsing ecosystems.

Damaged Main Spillway Of Oroville Dam To Reopen Next Week

Oroville Dam’s heavily damaged main spillway is expected to resume releasing water a little more than a week from now as levels continue to rise in the reservoir. The state Department of Water Resources announced Wednesday that the battered concrete spillway is likely to begin water releases around March 17. At that point, the level in Lake Oroville is expected to have risen to 865 feet. That’s well below the point at which water would go over the adjacent emergency spillway, but several feet above the comfort level established by DWR acting director Bill Croyle.

 

When It Rains, Los Angeles Sends Billions Of Gallons Of ‘Free Liquid Gold’ Down The Drain

During one of this winter’s frequent storms, sheets of rainwater spilled from roofs, washed across sidewalks and down gutters into a sprawling network of underground storm drains that empty into the Los Angeles River channel. Normally a thin flow of treated sewage, the river swelled with mocha-colored runoff. For a time it poured into the Pacific Ocean at a rate of nearly 29 million gallons a minute.

BLOG: Senators Call For Equity and Competitiveness In New Water Bond Allocation

The Senate Natural Resources and Water Committee passed a proposed $3.5 billion water and parks bond measure Tuesday, with members calling for an assurance that if approved by California voters in 2018, the funds would be equitably distributed throughout the state. The bond, Senate Bill 5 by Sen. Pro Tem Kevin de León, D-Los Angeles, includes $500 million for flood protection investments that were just added after the recent floods to address the state’s urgent needs.

San Diego-Los Angeles Fault Could Produce 7.4 Earthquake

The Scripps Institution of Oceanography on Tuesday raised the attention level for two earthquake faults, saying they’re actually a single system that could produce devastating temblors affecting Tijuana to the Los Angeles region. If offshore segments of the Newport-Inglewood and Rose Canyon fault system ruptured, they could generate a magnitude 7.3 quake capable of damaging much of the Southern California coastline, according to the scientists at Scripps, which is part of UC San Diego.

USGS Updates Forecast Of When A Major Quake Might Strike LA Region

USGS geologist Kate Scharer led a team that investigated the timing of sand, mud and gravel deposits that were episodically ripped apart by earthquakes along the San Andreas Fault over the last 1,200 years. They found evidence of 10 ground-rupturing earthquakes between 800 A.D. and the last rupture in 1857. “In the area of the Grapevine we had a 100-mile or so stretch where we didn’t have good information on the timing of earthquakes back for the last thousand years or so,” Scharer said.

Calif. Tribe Wins Appeal In Landmark Water Case

A federal appeals court sided with the Agua Caliente Band of Cahuilla Indians on Tuesday in a landmark water case, upholding a ruling that the tribe has federally established rights to groundwater in the Coachella Valley. The decision by the Ninth Circuit Court of Appeals is likely to set an important precedent for tribes across the country. The three-judge panel upheld a 2015 ruling in which a judge backed the Agua Caliente tribe’s claim that it holds a federally granted “reserved right” to groundwater beneath its reservation in Palm Springs and surrounding areas.

 

Thousands of Californians Have Contaminated Water Coming From Taps

Some 700,000 Californians are currently being exposed to contaminated water at home or at school, according to the latest data from California’s Water Resources Control Board. NBC 7 discovered more than 3,000 of those residents are living in the San Diego region, often in poorer, rural communities located within areas of Potrero, Pauma Valley and Borrego Springs.
